SURF-PUMP.

Specification of Letters Patent.v Patented May 16, 1911.

Application filed August 13, 1910. Serial No. 576,976.

To all whom 'it may concern:

Be it known that I, GEORGE V. T. SNARE, a citizen of the United States,residing at Ocean Park, in the county of Los Angeles and State ofCalifornia, have invented certain new and useful Improvements in Surf'Pumps, of which the following is a specification.

This invention relates to improvements in pumps, and has particularreference to a wave actuated means for driving the pump.

The principal object of the invention, is to provide a device of thischaracter and of such construction, that the greatest amount of energyin incoming waves will be used to the greatest advantage.

Another object is to provide an impact element of such constructionandarrangement, that the weight together with the Jforce of the impactis directed downwardly against said element.

These and other objects will be apparent from the following descriptionand with particular reference to the accompanying drawings forming a`part of this specification, and in which,

Figure 1 is an end elevation of the device, Fig. 2 is a front elevation.

Heretofore, in devices of this character, it has been the commonpractice to provide a pivoted float of such construction andarrangement, that the incoming tide or waves were directed against theunder face of the float to raise the float in the operation of either awater pump or an air compressor. In such devices, it was necessary toprovide some gravity means for returning the ioat to its lowermostposition, thus requiring and eXpending a greater amount of powercontained in the waves in lifting the combined weights of the float andgravity means, and in this way, losing a great deal of the power. Now bymy device, I provide an elongated transversely concave impact element,which points shoreward, so that the impact of the waves directedthereagainst, will bear downward to operate means connected to the pump.

Specifically speaking and with particular reference to the drawing, Iprovide a plurality of suitably spaced concrete or other piles 10, inthe upper ends of which, are secured in any suitable manner, thejournals 11, adapted to receive a longitudinally arranged rock shaft 12.Secured to the shaft, by means of the clips 13 is an impact element 14,of a length slightly less than that of the shaft, and of a width thatone-half or more, will be below the water line A, and above the waterline and secured to the outer face of the member 14, is an auxiliaryimpact plate 14, which curves from the plate 14, as shown at 15. Thisauxiliary plate is adapted to receive the impact of the curl, whichtakes place in a `breaking wave, and incidentally supports sulticient ofthe water for a short space of time to help bear down the plate 14. At asuitable distance behind the pile 10 and directly in line therewith, isa second series of piles of similar construction 16, but of greaterheight, their upper ends 16 extending above the water line. On the upperends of these piles, are secured the journal brackets 17, to each ofwhich is pivotally secured, a walking beam lever 18, the pivot point onthe said bracket being the Vfulcrum of the said lever. The forward orlonger portion of the lever 18 is pivotally connected to the impactplate 14, by means of the links 19, so that when theplate 14 moves upand down on the shaft 12, the lever will be rocked. At a suitable pointbetween the piles 10 and 16, are arranged the' piles 20, of slightlyless height than the latter, and supporting onl its upper end a pump 21,the piston rod 22 of which is pivotally connected to the lever 18, at apoint 23. Thus the upward and downward movement of said lever, by meansof the operation of the plate 14, will reciprocate the piston 24 in thepump 21, the upward movement of said piston drawing in water through apipe 25, and discharging the water on its downward stroke through a pipe26, discharging from the opposite side of the pump. This pipe 26 maylead to any convenient point, where it is desired to store the water. Itwill of course be understood that an air-compressor may be substitutedfor this pump, in such case the action being the same, and not alteringthe principle of the device, the main aim being to utilize the weight ofthe water as well as the force to drive the fluid from the pump.Directly in line with the aforementioned piles, is arranged another setof piles 27, which have in their upper ends a suitable securing means,as an eye bolt 28, to which is secured one end of a spring 29, the otherend of which is secured to the adjacent end of the lever 18, and servesto draw that end of the lever downward into its normal position. (Fig.1.)

While I have shown two pumps, it will of course be understood that I donot limit myself to any particular number, or design of same, as thismay be varied according to circumstances.

In the operation of the device assuming that the piston 24: hasdescended, the spring 29 draws it up into the position shown in Fig. 1,thus filling the pump cylinder. The impact of the waves against theplate 14E, will cause said plate to move downwardly on its pivot,pulling downwardly on the longer end of the lever 18 through the mediumof the links 19 and causing the piston 24 to descend and force the waterthrough the pipe 26. It will of course be understood that the pump isprovided with suitable check valves.

From the foregoing, it will readily be seen, that I have provided asimple and effective device operable by waves, and one which may asreadily be used on a beach as on any other part of a coast.

It will be apparent that changes in the form, proportions and minordetails of construction may be resorted to without departing from thespirit or sacrificing any of the advantages of this invention.

To limit the downward movement of the impact element 14, I provide aseries of stop members 30, of any suitable construction, but preferablyof concrete and having their upper ends beveled as at 31.

`/Vhat is claimed is:

1. An actuating means for a surf pump comprising a plurality ofsupports, journals mounted on certain of said supports, a shaft journaled on one set of said supports, al concaved impact element on saidshaft andy movable therewith, levers mounted in the other of saidsupports, connections between said levers and said pump, connectionsbetween one end of said lever and the impact element, whereby said leveris moved to operate said pump, and means connected to the opposite endof said lever for returning the device to initial position.

2. An actuating device for a surf pump comprising a set of supportscarrying pumps, a second set of supports having levers journaled intheir upper ends, a third set of supports having a shaft,journaledthereon, an elongated and transversely concaved impact plate secured toand movable with said shaft, said levers having longer and shorterportions, connections between said plate and the longer portions of saidlevers, connections between the said longer portions and said pump, anda fourth set of supports carrying resilient means on their upper ends,said resilient means being also secured to the shorter portions of saidlevers.

3. Actuating means for Surf pump comprising a plurality of supports,journals mounted on certain of said supports, a shaft journaled oncertain other of said supports, a concaved impact element on said shaft,and movable therewith, levers mounted in the other of said journals,connections between said levers and said pump, connections between oneend of said levers and the impact element, whereby said lever is movedto operate said pump, means connected to one of said supports and to theopposite end of said lever for returning the device to initial position,and upwandly and outwardly curved auxiliary impact plates secured tosaid impact element.

In testimony whereof I affix my signature, in the presence of twowitnesses.
